I can usually spot an iPhone if I can see the screen and it's full of buttons (not just about 8 at the top). Cept now you can download an app for the iTouch which gives you a ton more apps/buttons/etc (I did, it's cool - you can download games, some free and some for a few bucks. Fun fun.). So yeah, hard to tell nowadays. Both nifty, anyway - I'd love an iPhone (mainly so I could use Internet anywhere, without hunting for WiFi networks - then I could actually USE half of the aforementioned apps on my iTouch when they're actually helpful (ie maps, directions...)), but the plans are just too expensive for how little I use my phone nowadays (truth be told, having my current cell phone is a complete waste of $35/month - only use it in town, since it barely works on island and doesn't work at all in my place since I'm in a basement).
